Raspberry Pi -安装picamera错误

Question

我想安装picamera，但是我得到了这个错误：

pi@rpi01-1:~ $ pip install picamera
Downloading/unpacking picamera
Cleaning up...
Exception:
Traceback (most recent call last):

Storing debug log for failure in /home/pi/.pip/pip.log

我试着升级系统：

sudo apt-get install picamera

但是我不能安装。我在尝试以下命令时遇到了同样的错误：

pip install picamera

有什么想法吗？
